IMPROVEMENT IN ASH-PANS FOR LOCOMOTIVES.

Specification forming part of Letters Patent No. 200,910, dated March 5,1878; application filed October 20, 1877. I

To all whom it may concern:

Be it known that I, J OHN B. HARRISON, of Cincinnati, Hamilton county,and State of Ohio, have invented a new and Improved Ash-Pan forLocomotives, of which the following is a specification:

The object of my invention is to provide a convenient means. of dumpingthe cinders and ashes from the fireplace of a locomotive onto the track,for ballasting purposes; also, of facilitating the cleaning of the fire,to prevent the choking up of the draft and burning of grate-bars, and ofinstantaneous extinction of the fire when the pumps fail to work and thewater gets too low in the boiler, or for other purposes.

The invention consists in forming the bottom of an ash-pan out of aseries of slats, pivoted at their ends and connected together, to beoperated for closing and opening by a rod, in the fashion of Venetianblinds, and in combination therewith of a water-pipe connected with thepump.

The invention will first be described in connection with the drawing,and then pointed out in the claim.

In the accompanying drawings, Figure 1 is a top view of my improvedash-pan, suitable for a locomotive fire-box. Fig. 2 is a section of thesame, taken on line .10 .r in Fig. 1.

Similar letters of reference indicate corresponding parts.

A A are the sides of the ash-pan. B B are the usual front and reardampers. O are the slats forming the bottom of the ash-pan. These areprovided with pivots at their ends, which work in holes or bearings onthe inside of the ash-pan, and are connected together by a rod or rods,D, pivoted to lugs C, of which one is attached to each slat C, so thatby moving the rod the slats will oscillate on their pivots, and be madeto open and close in the manner of an ordinary window-blind. One of thepivots of the slats 0 extends through the side A, and

is provided outside the ash-pan with a lever or crank, E, for operatingthe slats. The pivots of the slats O are centered upon thejunction-lines f of the movable bars G and the stationary bars F, thelatter being formed upon or attached one to each side A, and supportingthe pivots, while the former, Gr, serve as journal-cups, common to themall. The bar G is held in position on the bar F by the bracket H,inserted to clamp their ends, as seen in Fig. 2.

By removing the bracket H and the bar G the slats 0 may be taken out ina very short time when repairs are needed, either of the ash-pan or ofthe grate-bars above.

I is a perforated water-pipe surrounding the inside of the ash-pan, andconnected with the water-supply pump of the engine.

By turning on the water from the pipe I the ashes and cinders may becooled before dropped on the track; and, when occasion requires, thefire may be quickly put out by being dumped off the fire-grate into theash-pan, and then sprinkled with water from the pipe I. The fire thusbeing extinguished, its contents are dumped on the track by opening theslats O wherever required, and withouudanger of causing destruction bytire.

The slats O are made concave on their upper surface, as seen in thedrawing, in order to retain enough water from the pipe I to keep themfrom warping by the heat.

Having thus .descIibed my invention, I claim as new and desire to secureby Letters Patent- The combination, in a locomotive ash-pan, of theslats O, concaved on upper surface, and the water-supply pipes ornozzles I, substantially as shown and described, for the purposespecified.
